Use Logical Disk attributes to create situations that monitor information about disk drive partitions that have been assigned a drive letter. Logical disk is a multiple-instance attribute group. You cannot mix these attributes with those of any other multiple-instance attribute group.

% Disk Time The percentage of elapsed time that a logical disk has been busy servicing read and write requests. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. The value -1 indicates Unavailable.
% Disk Write Time The percentage of elapsed time that a logical disk drive has been busy servicing write requests.

Logical Disk Name The name of a logical disk. Valid format is a text string of up to 64 characters.
Logical Disk Name (Long) The long name of the logical disk. Valid format is a text string of up to 268 characters.
Physical Disk Number The number of the physical disk that contains this logical disk. This value is only provided for drives assigned as drive letters. If the logical disk is a mounted volume, this value will be "Mounted". Note: Mnt = Mounted.
Server Name The managed system name. The form should be hostname:agent_code.
Examples include spark:KNT or deux.raleigh.ibm.com:KNT.
In workspace queries, this attribute should be set equal to the value $NODE$ in order to populate the workspace with data. This attribute is generally not included in situations, unless there is a need to customize the situation for a specific managed system.
Timestamp The date and time the Tivoli Enterprise Monitoring Server samples the data.
